WATER
|
|
|
Without water, life as we know it cannot exist. Water is underpriced because for a big part of history it has been abundant and easily accessed. This is now changing.

AIR
|
|
|
Clean air is good for human health as well as fauna and flora. Many steps have been taken to reduce the problem of air pollution that we can see, but not enough for the air pollution like CO2 that we cannot see, yet still dangerous.

RESOURCES
|
|
|
Natural resources have helped power the industrial revolution and enabled massive improvements in quality of life, but there are limits because of both depletion and egradation of natural capital. Better use of resources is essential.

BIODIVERSITY
|
|
|
Biodiversity is important. Humankind has emerged over millions of years as a result of massive biodiversity and complex evolution. The future of life depends on the continuing health of the biosphere in all its manifestations.
|
|
ECOSYSTEMS
|
|
|
There is genius in the way ecosystems have evolved over millions of years to stabilize natural systems in a way that has enabled life as we know it. We should be concerned that in the past 200 years this stability is being compromised.
